Dinosaur Remains

Recent Finds and Research


As each year goes by there is always the possibility of an exciting fossil being discovered, or of one of our existing fossils in the collection being featured in a scientific paper. When this happens we will do our best to let you know about it. However excavation takes some time, as does research if it is to be done properly, and publication often needs to wait until a new article can be professionally reviewed and then printed or produced on-line.

Sometimes we need to wait before reporting a new find so that the initial research can be finished. Some of our viewers may notice that articles appear here after the year has gone by - that just means we were waiting for the research to be published. Although it may seem an unusual thing to do we would not wish to rush the announcement of new finds until the scientific research had been robustly done.

We hope you enjoy reading about our new discoveries.

Information on this page is researched and produced by Trevor Price (with contributions from Alex Peaker).

2013

Finds

Remains of the hind quarters and tail of an Island plant-eating dinosaur were donated this summer. The creature was found in the Wealden Group deposits of the West Wight and is still in 'articulation' with the tail, hips and legs intact.  Research will take place shortly to compare the animal with other known specimens.  This dinosaur type was recently the subject of some comparitive research using known bones from various museums, including those from Dinosaur Isle, but the new Island specimen should greatly add to our existing knowledge.  

Research

Research at the end of last year and earlier this year has identified a possible new exciting result for one of our existing dinosaurs.  We await the publication of the research. 

A new area of dinosaur footprints is in the process of being written up by staff member Trevor Price - when this has been published the information will be added to these pages. Further research on Island dinosaur footprints was announced at a conference in September and we await the publication of the conference proceedings in due course.

One of our older objects - 3 blocks of rock containing a number of vertebrae, ribs and shoulder girdle from a plesiosaur has been recognized as a new genus and species; so we can add another holotype to the list of fossils on display at Dinosaur Isle.

More recently the delicate nasal bones of the Island dinosaur Eotyrannus featured for comparison with a young dinosaur found in China; and one of our sauropod vertebrae is mentioned in a paper on African dinosaurs. Two of our delicate turtle skulls (from Sandownia harrisi and Helochelydra nopcsai) featured in another paper on a new Chinese turtle.

2012

Finds
IWCMS 2012.594A number of interesting fossils have been found so far this year. One of the more exciting has been the crown of a large dinosaur tooth found by a Tasmanian couple on holiday on the Island. It is pictured here on the beach at Yaverland shortly after it was found (£2 coin for scale). 

Now part of the collection (numbered IWCMS 2012.594) it is evidence for one of the largest meat-eating dinosaurs on the Island - Baryonyx.  Given the condition of the tooth there may be more remains to be found; so fingers crossed! The tooth was generously donated by Annette and John McCarthy.

Research

Research is continuing into two of our Wealden reptiles. Publication may take place in 2013. We will let you know the results. A review of some of the crabs and lobster fossils from the north coast of the Island has featured in a new paper (reference below).

2011

Finds
An excavation at the beginning of the year uncovered the remains of a partial skeleton of a large sauropod. It is likely to be the subject of research for many years. We will let you know what happens. The specimen has been numbered IWCMS.2010.20 and is currently being cleaned, conserved and partially reassembled. Skeletal remains currently consist of much of the pelvis, hind limb bones, pedal phalanges and claws, and a quantity of rib segments. A number of gastroliths (stomach stones) were also found in amongst the remains.

Research

Neural arch from anterior caudal vertebra.Research into a complex neural arch from an anterior caudal vertebra (MIWG.5384) has resulted in it being identified from a new rebbachisaurid (Dinosaur: Sauropoda) from the Wessex Formation of the Isle of Wight.

Originally collected by Steve Hutt in 1983, the bone has been carefully conserved due to its fragile nature.  The fossil came from the soft mudstones of the Lower Cretaceous Wessex Formation near Chilton Chine.  Although there is not enough material to give this creature a new name it is an important addition to the known European rebbachisaurid dinosaurs Demandasaurus and Histriasaurus boscarollii.  

Further specimens (from the Isle of Wight) of the small dinosaur Valdosaurus have been the subject of research that indicates that this dinosaur may have been more common than previously thought.

A detailed review of the Isle of Wight Cretaceous turtle Helochelydra nopcsai has been published by the Palaeontological Association. The skull has been preserved in remarkable detail which has enabled it to be compared with similar turtles found elsewhere.

2010

Finds
IWCMS.2010.7 Cycadeoid stem fragment.A fine specimen of a Wealden cycadeoid stem fragment was acquired from collector Andrew Cocks. When alive, over 120 milion years ago, it would have formed part of a pineapple-shaped plant with long frond-type leaves.

It has been numbered as IWCMS.2010.7.

The diamond shape patterns are similar to those that can be found in modern cycads and tree ferns. The five-pence coin is for scale - it is 18mm in diameter.

2005

Finds


Caulkicephalus trimicrodon
- a new species of flying reptile from the Isle of Wight.

New pterosaur from the Isle of Wight!
Around 122 million years ago, the carcase of a pterosaur was washed into the mud at the bottom of a river. It lay there undisturbed until a few years ago, when coastal erosion removed it from its rocky tomb. Parts of the skull and wing bones were found on the beach by several different local collectors. Other parts may have been washed away already.

Pterosaurs were winged reptiles that lived at the same time as dinosaurs. The earliest pterosaurs are found in Triassic rocks in Italy, around 235 million years old. They survived until the end of the Cretaceous Period, by which point many large forms existed, with wingspans of over 12 metres. The reason for their extinction 65 million years ago is a mystery, but it was the end for many other animal and plant groups on Earth.

The new pterosaur from Sandown Bay belongs to a family called the Ornithocheiridae (‘bird hand’). They are large pterosaurs with crested skulls, long pointed teeth, and wingspans of around 4-6 metres. Ornithocheirids have been found in Cretaceous rocks in many parts of the world, particularly the UK, Brazil and North Africa.

The Sandown pterosaur is different from any that have been previously discovered, so it has been given a new name: Caulkicephalus trimicrodon. The generic name is derived from ‘caulkhead’, the traditional local name for people who caulked ships in the Solent shipyards. The species trimicrodon refers to the three small teeth near the front of the jaw.

The bones, which include the braincase, upper jaw and wing bones, were found on Yaverland beach by G. Leng, T. Winch, D. Davies, M. New, M. Munt, and L. Steel. The new pterosaur is described in the latest issue of the scientific journal Cretaceous Research, by a scientific team including Dinosaur Isle Museum, University of Portsmouth and the Humboldt Museum in Berlin.

The research is published in:  Steel, L., Martill, D. M. Unwin, D. M. and Winch, J. D. 2005. A new pterodactyloid pterosaur from the Wessex Formation (Lower Cretaceous) of the Isle of Wight, England. Cretaceous Research. 25, 686-698.

The two images shown in Figures 3 and 4 show the right lateral view of the rostrum (or upper part of the jaw). The rostrum is in three parts as can be seen in the photograph (Figure 2). The sockets for the teeth show that there are two prominent forward facing teeth at the snout, with three larger teeth behind on each side. Just to the left of the fracture (Figure 4) are sockets for three small teeth on each side. It is this feature that gives the species its name (trimicrodon = three-small-teeth). From this point back the teeth are staggered in alternate positions as can be seen in the palatal views below and in Figure 2. The preserved part of the rostrum is 29cm in length.

School find - 7th July 2005
Crocodile toothOn the 7th July 2005 this large fossil crocodile tooth was found by James, a Year 5 pupil from Birdham C of E Primary School, Chichester. It was found during one of our guided school fossil walks. The tooth is 24 mm long from tip to base; it has longitudinal grooves and a near-circular cross section. It may be from a large crocodile similar to Goniopholis which was swimming in the rivers at Yaverland over 122 Million years ago. This is only the crown of the tooth, if the root was still there the tooth would have been much longer. Complete teeth are rare. Its black colouration is due to the fossilization process - the fossil tooth contains a number of black iron compounds. The tooth is amongst the biggest found on this beach.


Strange, but true!
CoproliteOn the 2nd June 2005 this strange object was picked up off the foreshore at Yaverland. It is 16 centimetres long and 6 centimetres thick. Scientifically it is a coprolite, or fossil dinosaur dung (from the Greek Kopros = dung, and lite = mineral, from lithos = stone). It contains the digested remains of a bony meal eaten over 122 million years ago on the Isle of Wight. The lump would have dropped onto the ground as a large steaming heap, from a carnivorous dinosaur. Before it could be disturbed it was covered in mud and fossilized. It remained in the rock for millions of years, until it was found among the pebbles. The biggest lump is 6 centimetres in diameter. You can still see bits of smashed bone amongst the larger lumps which provides evidence that the dinosaur it came from was a carnivore. The coprolite has been given the Museum number IWCMS 2005.85, so it should be available for research for many years.
